Excellent inhibitory activity of aromatic selenocyanates against phytopathogenic bacterium and structure–activity relationship

This study is the first to systematically demonstrate the potential antibacterial activity of aromatic selenocyanates against phytopathogens, both in vitro and in vivo, highlighting the -SeCN group as a critical motif for agrochemical design. These findings open new avenues for developing selenium-based antibacterial agents in agriculture. © 2026 Society of Chemical Industry.
